How to run multiple instances of VLC from command line
5 janvier 2014, par AndyI have a vlc line that streams and transcodes a channel from tvheadend. Usually multiple streams are handled through VLM but for some reason VLM doesnt like tvheadend playlists. If I do this through command line it seems to be working fine
The command is ./vlc + some options
When you execute the command it returns a lot of output messages and you can not enter any other commands. I have successfully launched another line in a new putty session.
Is there a way to run this as batch to execute multiple VLC commands as if they were coming from different SSH sessions ?
Perhaps ffmpeg handles tvheadend playlists better ? -

how to use ffmpeg with mjpeg_vaapi encoder (with hardware acceleration) ?
8 août 2018, par MaratWhen I use ffmpeg with mjpeg encoder without hardware acceleration, everything works fine. I use following command :
ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg -vframes 1 pipe:1
But, when I try to use mjpeg with hardware acceleration, I always get error :
ffmpeg -nostdin -rtsp_transport udp_multicast -allowed_media_types 'video' -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i 'rtsp://MYIP' -ss 00:00:0.00 -f image2pipe -q:v 24 -vf scale=-2:480,format=yuv420p -c:v mjpeg_vaapi -vframes 1 pipe:1
